WATER-GATE.

SPECIFICATION forming part of Letters Patent N o. 734,385, dated J u1y^21 1903.

asuman met December 2, 1962.

To a/ZZ whom, t mctyconcern.: I

Beit known that LLINNAEUS W1NANs,a citi-l zen of the United Statesyresiding at Hood River, in the county of'Wasco and State of Oregon, have invented new and useful Improvements in Water-Gates, of which the following is aspeciiicationg- My invention relatestonew and useful improvements in water-,gates for use in' millraces, irrigating systems, canals, &;c.; and its object is to provide a counterbalanced gate adapted to be easily opened or closed ,and proj, vided with mechanism. ofrnovel construction for locking it in closed'position.

Another object is to lprovide means for pro.- tecting the gate whenopen from injury by logs or other large and heavy objects ap;` proaching the same. y

With the above and other objects in view, the invention consists in the novel construc-r tion and arrangement of the several parts, which will be nmore fully hereinafter de=` scribed and claimed. ,Y

In the drawings, Figure l is a side elevation of a flume having my improved Vgate therein; Fig. 2 is a section online :t .x of. Fig. 1. Fig. 3 is a plan view ofthe. gate in positionwithin the flume, the bridge yupon said iiume being broken away to disclose` the gate and its operating mechanism. Fig. 4 is a view similar to Fig. 3, but showingthegatelopen.

y Fig. 5 is a section on lineg/ 'y of Fig. 2, and

Fig. 6 is an elevation ofthe gate with one face thereof removed. 'if Referring to the -iigures by numerals of reference, 1 1 are uprights, preferably braced by means of inclined beamsv 2 and boarded up upon `their inner faces to form Walls 3 of the liume. A bridge 4 is arranged upon' these walls, and my improved gateis adapted togbe. arranged at a point below said bridge and upon the bottom 5 of the flume. The gate preferably comprises a centrally-,located vertical beam 6 and parallel end strips?. said-y central beam and end strips being braced bymeans of an inclined beam 8as shown in Fig. 6. These beams are preferably boxed in by boards 9 suitably secured V.tom opposite sides thereof, and as the beam G'isof greater thickness than the end strips 7the faces of the gate are curved or tapered toward the sides, as shown in Figs. 3, 4, and 5.

ferred to.

lower endnof the upright beam 6 is provided with a preferable metal stud 10, mounted in suitable bearings in the bottom 5 of the flume, and a similar stud 11 is formed atthewupper end of.. said beam and extends through the bridge 4and into an angular head 12, xed to said stud.

. The two edges of the gate are beveled upon opposite sides, respectively, as shown at 13, and these inclined faces are adapted to abut against beveled strips 14, arranged vertically on the inner facesof the walls 3 and at 0p- 'posit'esidesof the center of the gate. These strips serve to limit the movement of the gate upon its bearings and forni a tight joint therewith to prevent the escape ot' water therebetween. V llhen the gate is closed, it is adapted to be locked in such "position by means of novel mechanism. This mechanism comprises a vertical rod 15, journaled in brackets 1G, secured to the inner face of one of the walls ofthe flume and having a series of, short arms 17 extending laterally therefrom. The rod is adapted to be revolved by means of ahand-wheel-lS, arranged at the end thereof at apoint above the bridge 4. This rod is arranged at such ya distance from the adjacent strip 14that when the gate is moved into closed position against said strip lthe arms 17 can be swung back of the gate and wil-l hold the same ,firmly pressed against the strip.

The gat-e may be operated in any desired manner,'as bymeansof a windlass 19, mounted lo n standards 20, arranged on the bridge 4. A cable 2lis coiled upon this windlass and extends in opposite directions down through the bridge and over pulleys 22 to the ends of the gate. These pulleysare so located that when the windlass isturnedin one direction the gate will be swung open upon its pivot, while when the windlass is turned in the opposite direction said gate will be closed. lf desired, however, instead of employing the compliate'd'mechanism described,an ordinary sweep may be secured to the head 12, before re- A guide-wall 23 ispreferablylocated in the center of the fiume and parallel to the walls thereof. The end of thisguidewall is arranged 'at a distance `lfrm'the center of the gate equal toene-half the width of The said gate, and it is obvious that when the gate is opened it will substantially appear as a continuation of the wall 23. This wall serves to protect the gate while open from injury by logs or other heavy articles floating upon the water.

In operation when it is desired to close the gate either the windlass 19 is revolved or a sweep is placed upon the head 12, as the case may be. The gate is then swung open upon its center, and as the resistance of the water is the same at both sides of the pivot thereof it can be easily moved until its ends come into contact with the strips 14. The rod 15 is then turned by means of its operatingwheel 18, and arms 17 are swung into contact with the edge of the gate and force the same firmly against strips 14. These locking-arms 17 will absolutely prevent the reopening of the gate until they are again swung out of the path thereof. I preferably provide a wearplate 24 upon that edge of 'the gate which is operated upon by the arms 17.

As the distances from the central beams 6 to the ends of the gate are equal, the pressure of water upon opposite sides of said gate will also be equal at all times, and it is therefore obvious that the gate can be partly opened and left in such position without the use of locking mechanism.

In the foregoing description I have shown 1 the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein Without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes as fall within the scope of my invention.

Having thus described the invention, what is claimed as new is- 1. In a gate of the character described, the combination with the walls of a iiume, of a gate mounted upon a vertical centrally-located pivot, means upon the walls for sustaining the gate in closed position against pressure in one direction.

2. In a gate of the character described, the combination with the walls of a iium-e, of a gate mounted therebetween upon a vertical centrally-located pivot, strips upon said walls for limiting the movement of the gate and sustaining it in closed position across the fiume against pressure in one direction, and means for clamping and locking the gate against said strips.

3. In a gate of the character described, the combination with the walls of a fiume; of a gate having a pivot at a point eqnidistant from the ends thereof, said pivot being located in the center of the fiume, strips upon the walls of the flu me adapted to be contacted by and to limit the movement of the gate, a revolving rodjonrnaled upon one of saidwalls, and arms thereto adapted to clamp and lock the ends of the gate against said strips.

4. In a gate of the character described, the combination with the walls of a fiume, of a gate therein comprising a central beam, end strips parallel thereto and at equal distances therefrom, curved faces to the gate connecting said beams and strips, said faces being tapered toward each other at the ends, beveled ends to the gate, beveledstrips upon the walls of the flume adapted to contact with the ends of said'gate and limit its movement, and means for locking said ends upon the strips.

5. In a gate of the character described, the combination with the walls of a fiume; of a gate pivoted inthe center thereof and having its pivot located at a point equidistant from its ends, beveled ends to said gate, heveled strips upon the walls of the flume, a revoluble rod upon one of said walls, and arms extending from said rod and adapted to clamp and lock the said ends against the strips.

(i. In a gate of the character described, the combination with the walls of a fiume, of a gate pivoted at the center of the iiume and having a vertical pivot at a point equidistant from its ends, strips upon the walls of the flume adapted tov limit the movement of the gate upon its pivot, means for clamping and locking said strips, a windlass, anda flexible connection between the windlass and the ends of the gate, whereby said gate may be swung upon its pivot.

7. lIn a gate of the character described, the combination with the walls of a flume; of a guard-wall in the center of said flume and parallel with the walls thereof, a gate pivoted between the walls of the fiume and at a point in alinement with the guard-wall, said pivot being vertical and arranged at a point equidistant from the ends of the gate, means for limiting the movement of the gate upon its pivot, and locking-arms pivoted to one wall of the fiume and adapted to hold thegate in closed position.

In testimony whereof I affix my signature in presence of two witnesses.
